This invention relates to glide fasteners of the type particularly adapted to serve as closures for cosmetic pouches and the like although the invention may be as eifectively employed as closure means on other articles.

Much effort has been expended in the design and construction of pouches for powder puifs, tobacco, and the like, and bathing bags, handbags, and purses, which employed sliders or gliders as closure means. Invariably, the sliders or gliders were tied together as by means of tapes, cords, or chains whereby uniform spacing thereof was obtained in the closed conditioner the pouch or bag. Telescoping closure members were also employed for this purpose but provided an undesired rigidity to the articles upon which they were used. In both instances the structures were quite expensive and frequently their sale was impeded because of their high cost and complicated structure.

Recognizing the above stated faults, the present invention has for its primary object the provision of fastener means of the indicated type which is characterized by simplicity and low production cost.

Another object of the invention is to provide sliders or gliders for pouches and bags which are not physically connected but which will assume properly and uniformly spaced positions when serving to close a pouch or bag.

The foregoing general objects and other objects, features, and advantages of the invention will become more clearly apparent from the following specification in which various forms of the invention are detailed and which has basis on the accompanying drawing illustrating several preferred embodiments as at present conceived.

In the drawing:

Fig. 1 is a side view of a pouch or bag, partly broken away, incorporating a preferred form of the invention, the sliders or gliders being shown in pouch or bag closing position. y

Fig. 2 is a similar view with the sliders or gliders bunched to permit ready access to the interior of the pouch or bag.

Fig. 3 is an enlarged sectional View as taken on the line 3-3 of Fig. 1.

Fig. 4 is a similar View as taken on the line 4--4 of Fig. 2.

Fig. 5 is a plan view of the upper portion of the pouch or bag in open or pattern condition and before forming thereof.

Fig. 6 is a view similar to Fig. 1 illustrating a modified structure.

Fig. '7 is an enlarged sectional view as taken on the line I-l of Fig. 6.

Figs. 8 and 9 are sectional views showing two of a set of sliders or gliders of alternate form.

Figs. 10 and 11, 12 and 13, and 14 and 15 are detail views showing alternate forms of sliders or gliders, two of a set of sliders are shown in each instance.

Fig. 16 is an end view of the slider shown in Fig. 15.

Fig. 17 is a detail perspective view, partly in cross-section, of a pouch formed with an alternate form of rim.

In that form of the invention which is illustrated in Figs. 1 to 5, the bag or pouch 2E! is made with a mouth to give access to the interior thereof. This mouth is usually dened by abead or welt. In the present instance, it is preferred to substitute a wedge-shaped vmember 2| at this point and to enclose said member in the material of the bag or pouch to provide a rim 22 which is wider at one end 23 and tapers to a relatively lesser width at the opposite end 24. As shown in Fig. 5, the member 2l is rst enclosed in the material of the bag or pouch which is then folded along the dotted line 25 during the forming of the bag or pouch, the opposed ends 25 being stitched together as well known. It should be understood that while this structure is preferred, the member 2l may also be made in two pieces and may have a cross-section other than tha-t shown. For instance, Fig. 17 shows the wedge-shaped memberor members Zia as round in cross-section and may be formed by a tapered cord or the like or may be formed by rolling a bias cut piece of material into the desired wedge shape. Further, the riminstead of having the side to side relation shown, may have top abutting relation, in which instance the sliders hereinafter disclosed would be designed with two similar ends for engagement with each run of the rim separately. It is also obvious that the rim thus provided may be formed as separate stringere, which may be applied to a bag or pouch in the same manner as hookless fastener tapes are applied.

When the bag or pouch is thus completed, a set of sliders or gliders is provided. These are designated 21, 28, 29, and 3B, and while four are shown, it is obvious that any suitable number may be used. The sliders are assembled by slipping them onto the rim 22 from the narrow end 24 thereof and in the order stated.

These sliders may be bent or formed of sheet metal or they may be stamped, cast or otherwise formed of solid material.

Each of the sliders is preferably, though not necessarily, the same height but each is provided with an opening 3| different in height than the height of the opening in each of the others. Thus, the opening in the slider 21 is greatest in height, the height of the opening in the slider 28 somewhat less, and so forth. It is evident, then, that each opening height is made in accordance with the width of the rirn 22 at the point where it is desired to have the slider come to rest when the bag or pouch is in closed condition.

When the sliders are assembled on the pouch, the one nearest the narrow end 24 of the rim is aflixed thereto as by clinching or any suitable manner. For this purpose a separate fastener clip may be employed if desired. The other sliders are then free to be moved along said rim until the heights of their openings 3| cause the respective top and bottom walls 32 and 33 thereof to Wedge against the respective top and bottom edges 34 and 35 of the rim. When this occurs, each succeeding glider will come to rest and hold the rim closed until the nal slider (in this case 21) wedges into position. The pouch is now closed.

To open the pouch it is only necessary `to slide the slider 21 back along the rim towards the fixed slider 30. As the slider 21 progresses, it will pick up the others in turn until the condition of Fig. 2 is obtained. The pouch is now open for access to the interior thereof.

As shown in Figs. 3 and 4 and in Figs. 12 and 13, the sliders may be made of plastics, wood,

cast metal, or in other such solid forms, and

may be made with their bottom portions 36 different in height as shown in Figs. 1 and 2 or with their top portions 31 different as shown in Figs. 12 and 13.

Fig. 6 illustrates a form of the invention in which the rim 38 is provided with progressively wider portions 39, 43, 4| and 42. Thus the slider 43 will come to rest against the abutment formed by the portion 39 and be clinched or otherwise permanently positioned into place at this point, and the other sliders 44, 45, and 43 will successively be stopped by the abutments formed by the portions 4B, 4|, and 42. In this form also, as shown in Fig. '7, the slides are made of sheet metal and leg portions 41 provided to engage the mentioned abutments. Thus, the height of these leg portions determines which abutment will be engaged to bring a slider to rest in pouch closing position.

Variations in the forming of the sliders are shown in Figs. 10 and 11 wherein the leg portions are further bent at 48 to engage the side Walls of the slider, and in Figs. 14 and l5, wherein differently positioned teats 49 may serve to engage and wedge the bottom edge 35 of the pouch rim.

As shown in Figs. 8 and 9, only one run of the rim may be formed wedge shaped as in Fig. 1 or stepped as in Fig. 6, the other being of uniform width as shown at 50. With a pouch so constructed, one wall of the sliders may be the same in height while the other wall 52 of each varies as above set forth.

While several forms of the invention have been disclosed, they by no means exhaust the possible various forms which may be made within the spirit of the invention as dened by the following claims.

What I claim as new and desire to secure by Letters Patent, is:

1. A bag, pouch, or the like comprising a rim which is wider at one end than at the other, said rim being formed with progressively narrower parallel portions, and a plurality of disconnected fastener members slidably engaged with said rim.

2. A fastener for a bag, pouch or the like which has a rim that is wider at one end than at the other, comprising a plurality of disconnected fastener members slidably engaged with said rim,

.each of said members being formed with an opening different in height from that of the other openings, different portions of said rim being engageable with the walls of the openings of successive members to wedge said members to said rim at different points thereof.

3. A closure fastener for a bag, pouch or the like having a rim which is wider at one end than at the other, comprising a set of independent, disconnected closure members slidably arranged on said rim, each closure member being formed with an opening in which the rim is engaged and each opening being different in height from that of the others.
